Martin has been managing and investing in a range of insurance and financial services companies since 1985. He is chairman of the Vantage Group of Companies, and also chairman and beneficial owner of the Polygon Group – a group that invests in European, UK and Channel Island property and businesses.
Previously Managing Director of Guernsey based Polygon Insurance Company Limited, which was originally an aviation insurer, he spearheaded the development and diversification into captive insurance management, insurance broking and trust administration. In 2001, Martin led a management buyout and formed the basis for a new company, Heritage Group where, as CEO, he drove its rapid expansion from 2001 to 2008 into a multi-jurisdictional financial services company.
Polygon Insurance Company continued trading and Martin then moved from CEO of Heritage to non-executive chairman of Heritage in order to focus on developing opportunities at Polygon. Since 2009 Martin has rapidly transformed Polygon, building up its investment portfolio which now includes property, operating companies (both regulated and non-regulated) as well as a number of "business angel" investments into start-up companies.
